Planning An Ergonomic Work Space
Before you set up your new computer, find the best location for your new computer and plan your work space. There are
several ergonomic factors to consider when you arrange your work space:
 Stable work surface—Use a stable work surface large enough to support the computer and other peripheral
equipment.
 Ventilation—Leave at least eight inches of space on both sides of your computer and at least 5 inches of clearance
for the back.
 Placement of the mouse and other input devices—Place your computer, mouse, or other input devices so that your
arms and hands are in a relaxed, comfortable position. The computer's keyboard should be directly in front of you.
Keep your wrists in a relaxed position when you are using the keyboard—not angled up or down. Position the
mouse at the same level as the keyboard. Hold the mouse with a relaxed hand, and use your whole arm to move it.
Take breaks during sessions with your computer. Excessive use of the mouse or a joystick may strain muscles or
tendons.
 Furniture and posture—Sit in a chair with good back support and armrests. Adjust the level of the chair so your feet
are flat on the floor. A footrest may make you more comfortable. Sit with relaxed, upright posture—avoid slouching
forward or leaning far backward.
 Viewing angle of the display—Position the unit so that the display is 18 to 26 inches directly in front of you, with
the top of the screen at or a little below eye level. Use the display's tilting feature to find the best position. You can
reduce eye strain and muscle fatigue by placing the display in the proper position.
 Lighting—Choose a location where windows and lights do not create glare and reflection on the display. Use
indirect lighting to avoid bright spots on the display. You can also purchase accessories for your display that help
reduce glare. Proper lighting adds to your comfort and work effectiveness.
